Pendulum2 now a peg is placed 4/5 of the way down the pendulum’s path so that when the mass falls to its vertical position it hits and wraps around the peg. how fast is the mass moving when it is at the same vertical height as the peg (directly to the right of the peg)? m/s submit 5) return to the original mass. what is the tension in the string at the same vertical height as the peg (directly to the right of the peg)? n submit

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
